 I'm not convinced that abusing unit tests this way is the best
 approach, but as the existing tests already passed the review-merge
 process I won't fight against that at this moment.

 The most important and urgent issue is to fix the occasional
 failures.  If we can do this by tweaking the test case I'm okay with
 it for the purpose of this ticket.  I reserve the opinion of
 revisiting the approach itself, though.

 BTW, this doesn't seem to be OpenBSD specific.
